Description
Technical field
The present invention relates to a kind of anticorrosive paint and preparation method thereof, particularly relate to a kind of hyperbranched polyether type epoxy resin/
Epoxy resin composite anticorrosion coating and preparation method thereof, belongs to anticorrosive paint technical field.
Technical background
Epoxy coating has a very wide range of applications in paint field due to adhesive force and the chemical resistance of its excellence.
But under height corrosion requirement condition, the acid resistance of conventional epoxy coating and salt spray resistance are not met by its application.Therefore,
In in the past few decades, people have done substantial amounts of research in modified conventional epoxy anticorrosive paint field.So far, Ren Menyan
Studied carefully by other polymeric materials such as polyamide (Zhang H, Wang J, Liu X, Wang Z, and Wang S,
Ind.Eng.Chem.Res.2013,52,10172), polyurethane (Mishra R S, Khanna A S.Progress in
Organic Coatings, 2011,72,769), inorganic particulate (Sabagh S, Bahramian A R, Kokabi
M.Iranian Polymer Journal, 2012,21,837) and dissaving polymer (US 2008/0289539 Al) etc. with
Physical blending or chemically combined mode are incorporated into the antiseptic property improving epoxy coating in conventional epoxy coating.Physical blending
Method improve the mechanism of antiseptic property of coating and be mechanical masking effect, the method for chemical modification is then to be to improve tree
The compactness of aliphatic radical volume grid.Therefore, from the point of view of life-time service, the method for chemical modification has more advantage.Chemical modification
Method being most commonly used that, addition dissaving polymer is modified.Hyperbranched polyether type epoxy resin has the class spherical junctions of three-dimensional
Structure, gives its viscosity low, and dissolubility is good, the feature that end group number is many.The feature that viscosity is low and dissolubility is good makes hyperbranched poly
Compound is expected to reduce the solvent usage amount of paint film；The feature of many end groups number can make the crosslink density of paint film increase, thus increases
Add the compactness of paint film.Therefore dissaving polymer more and more causes the extensive concern of people in paint field.
Hyperbranched poly ester polyol and melmac are combined the anticorrosive paint of preparation by Gunasekaran G. et al. research to be had
Excellent mechanical performance and antiseptic property, salt spray resistance reaches 600h.Tsiourvas et al. is by hyperbranched polyethyleneimine and ring
Epoxy resins is combined the anticorrosive paint of preparation, and evaluates antiseptic property with electrochemical impedance spectroscopy (EIS), and result shows to the addition of over-expense
The antiseptic property of the paint film changed is substantially better than unmodified paint film, and soaks (0.35wt.% (NH4)2SO4And 0.05wt.%NaCl)
8 weeks later paint films of solution do not have any change substantially.As far as we know, the dissaving polymer in paint film field is applied at present
Great majority are hyperbranched poly esters, and ester bond easily hydrolyzes, and chemical-resistant is poor.Compare with hyper-branched polyester, hyperbranched
Polyethers has that chemical-resistant is good and the ehter bond of tenacity excellent, advantageous in paint field, and application hyperbranched polyether is modified
The research of corrosion-resistant epoxy paint have not been reported.
